I'm wanting to go to efi on my 4.2. I really like the Performance Fuel injection system offers for the money. Has anyone used them? The other part of this is best way to get fuel to it reliably without installing a new tank. I've read the baffle issues, surge tank solutions and so on. I have a cj with the 4.0 conversion and a frame mounted electric pump at the tank and have never had a problem in four years. Is fuel delivery really that big a problem if your not keeping it at extreme angles for long periods?

I looked into this system along with a few others using almost the same components, this is a cobbled together rehash of gm parts most vintage 1988- 1996 it's not customizable like the holley sniper efi/hyperspark system that allows you to change rpm, fuel ratio, timing, all from the cab, where as this system you have to have them program the chip, and it's a fixed program, for the extra money you spend you get so much more with the holley.
